JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 771,048, datedSeptember 27, 1904. Application filed May 11, 1903. Serial No. 156,514.(No model.)

To all whom it may concern.-

Be-it known that 1, WILLIAM H. EMERIcK, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Journal-Boxes, of which thefollowing is a specification.

My invention relates to-improvements in journal-boxes for railway-cars.

Railway journal-boxes as heretofore constructed have at their rear endsan integral wearing face, flange, or collar which bears against theWearing boss or face of the carwheel and confines in place the dustguard, which surrounds the axle to prevent dust, sand, and grit fromgetting into the journal and its packing. Owing to the end thrustbetween the car-axle and journalbox, especially in rounding curves, thefriction is great of the car-wheel upon this integral Wearing face,flange, or collar at the end of the journal-box, so that in a short timethe metal is partially or entirely cut away, so that the wearing flangeor collar is broken off or worn away, thus permitting the dust-guard tofall or get out of its proper position, so that the journal will quicklyfill with sand and grit sucked up from the track, resulting in heatingand destruction of the journal-bearing and sometimes in seriousaccidents occasioned thereby, and when the wearing face, flange, or bossat the rear end of the journal-box becomes thus worn or broken it isnecessary to remove and throw away the entire journalbox and replace itwith a new one, thus involving not only great expense, but alsounavoidable delays in the movement of trains.

The object of my invention is to provide a journal-box of a simple,strong, efficient, and durable construction that will effectuallyovercome these difliculties or objections.

My invention consists in the means I e'mploy to practically accomplishthis object or resultthat is to say, it consists in providing thejournal-box with a removable wearing face or piece at its rear end madein a separate piece from the journal-box and connected thereto byinterengaging guides.

It further consists in combination, with the journal-box, of a removablewearing face or piece therefor at the rear end thereof made in twoseparate pieces or parts, so that the same can be removed or appliedaround the axle without removing the journal-box.

It further consists, in connection with the axle and journal-box and itstwo-part removable wearing face or piece, of a dust-guard confined andheld in place at the rear end of the journal-box by the removablewearing face or piece of the journal-box.

It also consists in the novel construction of parts and devices and inthe novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification,Figure 1 is a central vertical section of a journal-box embodying myinvention. Fig. 2 is a top or plan view. Fig. 3 is a central horizontalsection. Fig. 4 is a section on line 4 4 of Fig. 3, and Fig. 5 is adetailed perspective view of one half or part of the removable wearingface or piece of the journal-box.

In the drawings, A represents a car-axle, A a portion of a car-wheel,and a the wearing face or boss thereof, which bears against the end ofthe journal-box.

B is the journal-box, and C the bearing therein fitting the journal atof the axle. The journal-box B is provided at its rear end with aremovable or independent wearing face or piece D, made in a separatepiece from the journal-box and preferably made in two halves or parts,both of which are designated by the reference-letter D, and removablyconnected to the rear end of the journal-box by interengaging guides (Z5, formed on the removable wearing face or piece D and journal-box,respectively. These guides b d preferably consist of inter-engaginggrooves and shoulders or ribs, as illustrated in the drawings, andextend all around or at the sides, top, and bottom of said parts B andD. Bolts d, having nuts d extending vertically through the two halves orparts D l) of the removable wearing face or piece, secure the sametogether and to the journal-box around the axle. The removable wearingface or piece D D of the journal-box may also be secured thereto by lugsor pins 6 on the journal-box,

having keys 5, and which lugs or pins exi tend through suitable holes (1in the lateral flanges d" of the removable wearing face or piece D ofthe journal-box. The wearing face or piece D of the journal-box, or eachhalf or part thereof, comprises a lateral or marginal flange (Z whichsurrounds and embraces the end of the journal-box at its horizontal,top, bottom, and upright sides, and an upright end flange d, which bearsagainst the wearing face or boss of the car-wheel and which, inconnection with the end flange Not the journal-box, forms a chamber F toreceive and confine the dust-guard F.

The two-part removable wearing-piece D D when the two members thereofare clamped together is of a general box shape and surrounds andincloses the end of the journalbox, the lateral flanges d at the top,bottom, and upright sides of the wearing-piece overlapping andsurrounding the end of the journal-box and forming a tight jointtherewith by the interengaging guide-grooves and shoulders b d on thejournal-box and on the lateral flanges of the wearing-piece,respectively.

The dust-guard F may be of any suitable construction, but is preferablycomposed of two halves or parts, each designated by the reference-letterF and each preferably consisting of an independently-movablc shell f,embracing a felt or other packing f, the two halves or parts F F beingcontinually forced together around the axle by springs f f, which areinterposed between the shells f and the removable wearing face orpiece 1) D of the journal-box.

B represents the lid or door of the journalbox.

I claim 1. The combination with a car wheel and axle and dust-guard, ofa journal-box provided at its rear end with a removable wearing-piece tobear against the wearing-boss of the car-wheel, and to confine thedust-guard in place around the axle, said wearing-1:)iece comprising twoduplicate members having lateral flanges surrounding and engaging therear end of the journal-box at its top, bottom and upright sides, andhaving upright end flanges to bear against the wearing-boss of thecar-wheel, said members having also bolts passing through the same oneon each side of the axle to removably clamp and unite the same to thejournal-box, substantially as specified.

2. The combination with a car wheel and axle, of a journal-box and aremovable, twopart, box-shaped wearing-piece secured thereto at theinner end thereof, and comprising duplicate members having lateralflanges embracing and surrounding the inner end of the journal-box atits top, bottom and sides, said lateral flanges and inner end of thejournalbox having interengaging guide shoulders and grooves, saidmembers of the wearingpiece also each having an upright end flange tobear against the wearing-boss of the carwheel, and boltsextendingthrough both members of the wearing-piece, one on each side ofthe axle for removably connecting and clamping the two-partwearing-piece to the journalbox, substantially as specified.

3. The combination with a car wheel and axle, of a journal-box providedat its rear end with a removable wearing-piece to bear against thewearing-boss of the car-wheel, and to confine the dust-guard in placearound the axle, said wearing-piece comprising two duplicate membershaving lateral flanges surrounding and engaging the rear end of thejournal-box at its top, bottom and upright sides, and having upright endflanges to bear against the wearing-boss of the car-Wheel, said membershaving also bolts passing through the same one on each side of the axleto removably clamp and unite the same to the journal-box, a two-partdust-guard interposed between the journal-box and said two-partwearing-piece, and springs for pressing the two parts of the dust-guardtogether around the axle, one spring acting on the upper member of thedust-guard and the other upon the lower member, substantially asspecified.
